Title: Remotely controlled hydraulic gear - has pressure chambers connected to supply via throttles and constant flow remote control valve
IPC: F15B11/10
Filed: 1974-08-28
Abstract: Some of the shortcomings of prior designs are the relatively large sizes of the pressure chamber in order to obtain large control forces with low supply pressures resulting in slow reaction times and prolonged positioning times. High ambient temps. can further increase the extent of these shortcomings due to the reducing valves controlling the main control valve without an additional amplifier. By maintaining a constant flow through the control lines the effect of temp. on the reaction and positioning times is reduced. The arrangement features only three lines leading to the control post.

Filed: 1977-05-13
Abstract: Cette invention concerne l'utilisation d'un composé chimique particulier, le 1-triacontanol de formule CH3 (CH2 )28 CH2 OH comme régulateur de la croissance des plantes. Le triacontanol agit comme stimulant de la croissance sur une large gamme de plantes en augmentant les gains de poids sec, l'absorption d'eau, l'efficacité de l'utilisation de l'eau et la synthèse des protéines dans les plants traités. Le triacontanol peut être appliqué de différentes façons avec une égale efficacité, par exemple sous forme d'une pulvérisation sur les feuilles, sous forme d'un arrosage du sol, sous forme de produits introduits au niveau des racines ou en faisant partie d'une composition d'insecticide ou d'engrais, etc. On a trouvé de manière surprenante que les plants traités au triacontanol et cultivés à l'obscurité voient leurs surfaces de feuilles et leur poids sec augmenter et que les plans traités continuent à synthétiser les protéines. La figure 4 est un exemple de résultats obtenus en utilisant le triacontanol.
Patent FR-2353657-A1 (FR)
IPC: C25D11/38
Filed: 1977-06-01
Abstract: A method of producing chromium conversion coatings is described. The coatings are novel in that they are chromite i.e. Cr2O3 coatings rather than the conventional chromate i.e. CrO3 coatings. The invention includes a novel electrolyte for depositing chromite layers. The electrolyte is an aqueous solution containing CrIIIions, a weak complexing agent for CrIIIions and a poison for the electrodeposition of chromium metal. The electrolyte preferably also contains conductivity salts and may include other additives such as fluoride ion and boric acid. Examples of poisons are CrVIions, peroxide, nitrate, polyamines, phosphates and formaldehyde. The chromite conversion coatings can be improved by aging and can be subsequently painted or lacquered. The electrolytes of the present invention are much less corrosive than CrVI electrolytes and thus the substrates which can be coated include materials which cannot readily be chromate coated because they are reactive towards CrVI electrolytes.
